Katha (unit)

A katha (also spelled kattha or cottah; Hindi: कट्ठा, Bengali: কাঠা) is a unit of area mostly used for land measure in Eastern India, Nepal, and Bangladesh. After metrication in the mid-20th century by both countries, the unit became officially obsolete. But this unit is still in use in much of Bangladesh and Eastern India and Nepal.

Not to be confused with the dye and food additive Catechu and the tree from which it is made Senegalia catechu

The measurement of katha varies significantly from place to place.

In Gorakhpur state 1 katha = 1361 sqft. The length of the area should be 40 ft and the breath should be 34.025 ft and length × breath = 1361 sqft.

In Bangladesh, one katha is standardized to 720 square feet (67 m2), and 20 katha equals 1 bigha.
